Deformation-based shape analysis of the hippocampus in the semantic variant of primary progressive aphasia and Alzheimer’s disease
(Elsevier, 2020-06-03)
Background
Increasing evidence shows that the semantic variant of primary progressive aphasia (svPPA) is characterized by hippocampal atrophy. However, less is known about disease-related morphological hippocampal changes. ...
The anatomy of category-specific object naming in neurodegenerative diseases
(Massachusetts Institute of Technology Press, 2006)
Neuropsychological studies suggest that knowledge about
living and nonliving objects is processed in separate brain regions. However, lesion and functional neuroimaging studies
have implicated different areas. To address ...
Rule violation errors are associated with right lateral prefrontal cortex atrophy in neurodegenerative disease
(Cambridge University Press, 2009)
Good cognitive performance requires adherence to rules specific to the task at hand. Patients with neurological disease often make rule violation errors, but the anatomical basis for rule violation during cognitive testing ...
Longitudinal gray matter contraction in three variants of primary progressive aphasia : a tensor-based morphometry study
(Elsevier, 2015-01-22)
The present study investigated the pattern of longitudinal changes in cognition and anatomy in three variants of primary progressive aphasia (PPA). Eight patients with the non-fluent variant of PPA (nfvPPA), 13 patients ...
